[email protected] Abstract. In this study, two new genera of Desmiphorini (Lamiinae) are proposed: Cleidaria gen. nov., to include Cleidaria cleidae sp. nov. from the state of Chiapas in Mexico, and Obscenoides gen. nov. for Desmiphora (D.) compta Martins & Galileo, 2005. The shape of tarsal claws of Cleidaria cleidae sp. nov. (abruptly narrowed from basal half) is so far, not found in any current genera of the tribe. With respect to Obscenoides compta (Martins & Galileo, 2005) comb. nov., the genitalia of males have an unusual shape with non-retractile parameres. The character combination related to this genital structure is unknown to us in other species in the family, and hypotheses about its function are suggested. Key-Words. Genital morphology; Longhorned beetles; New taxa; Taxonomy. INTRODUCTION the current definitions of some tribes, especially based on the works of Breuning do not take into Lamiinae (Cerambycidae), also known as flat- account adaptive convergences and use superfi- faced longhorns, with more than 21,000 described cial characters to subordinate taxa. species in about 3,000 genera and 87 tribes is Among these tribes, Desmiphorini Thomson, the largest subfamily of Cerambycidae occurring 1860 is not an exception, and its “boundaries” are worldwide (Tavakilian & Chevillotte, 2019).
